MACRO FILAMENTOUS ALGAE AS BIOINDICATORS IN THE LOWER OLIFANTS RIVERS
The poor water quality of Ga-Selati and Olifants Rivers favours the development, growth as well as the distribution of macrofilamentous algae species of Cladophora, Stigeoclonium and Oedogonium. In the Olifants river, changes in the water clarity has been observed in several attempts. Clear water conditions have decreased, and in many cases, the water is turbid for longer periods than expected. High turbid waters were often accompanied by high water flows during periods of high rainfall events and this contributes to SAV and macrofilamentous algae sloughing and scouring off even during periods of growth. Long term monitoring of SAV distribution and growth in these two river systems make historical data crucial in determining the frequencies and magnitudes of high water flows as they result in the drastic displacements of SAV and macro filamentous algae in the environment. Given the current state of the systems, the rivers are under severe pressure from mining, WWTWs, agricultural activities and the system has degraded. UAV mapping of SAV and macrofilamentous algae in the two river systems of Ga-Selati and Olifants improved the understanding on the complex behavior and development of the aquatic vegetation
